Yes, I also hope the developers spend a little more time on improving the custom battles. It has so much potential for testing things out and improving your skills. Also just for the fun of it. For instance, you on horseback, heavily armored, with a big glaive or something in you hands, against 100 looters. You can practice your horsemanship and how best to deal massive death with a polearm, while carving through multiple enemies with each swing. It may not be much of a challenge, but it sure would be fun.
